Lady Kitty took part in the photoshoot for Marie Claire Italia and she has published one of the pictures on her Instagram page for her 463,000 followers.
In the pictures, the 27-year-old is seen wearing a gold chain with cut outs taking the shape of leaves.
The high end jeweller Bvlgari designed the necklace, called Happy Leaves, and it comes from the ‘Wild Pop’ collection.
Lady Kitty said: “Best time shooting MarieClaireItalia with Alan Gelati. Wearing Bulgaria official.”
One fan commented on her Instagram picture saying: “I see so much of Diana in you, gorgeous!”
Lady Kitty made headlines in May when she went to her cousin Prince Harry’s wedding to Meghan Markle with many people saying she looked like Princess Diana.
The daughter of the Diana’s brother, Charles the 9th Earl of Spencer, modelled for Dolce and Gabbana in 2017.
In an interview with Vanity Fair, Kitty once said: “I was so young when Diana was alive.
“There are only a few memories, but special memories and happy memories, and I’m so lucky to have those.”
During her modelling career, she has worked for brands like Dolce and Gabbana and she has appeared in various ad campaigns.
Besides modelling, she works with several charities including Centrepoint, which supports homeless people.
The model has enjoyed a summer of travelling and has shared pictures to her 440,000 Instagram followers of a trip in St Tropez.
Kitty grew up in South Africa, reading psychology, politics and English at the University of Cape Town.
It is thought that she is fairly close to her cousins, the Duke of Cambridge and Sussex.
